You would have to go to each of the contest pages and find the instructable there and click vote below the thumbnail.For example for the Holiday gift contest go here: https://www.instructables.com/contest/gifts/?show=ENTRIES

For the Holiday decorations go here:https://www.instructables.com/contest/krylonwinter/?show=ENTRIES

Otherwise the contest banner on the instructable it self would only let you vote for the one contest.
